TOBACCO CARTRIDGE.

Specification of Letters Patent.

Patented Dec. 21, 1915.

Application filed November 20, 1915. Serial No. 62,520.

To all whom it may concern:

Be it known that I, CALI-3B C. DULA, a citizen of the United States,residing at Yonkers, in the county of Westchester and State of New York,have invented new and useful Improvements in Tobacco Cartridges, ofwhich the following is a specification. 1

My present invention relates generally to tobacco products and moreparticularly to a distinctly new tobacco charge or ca tridge especiallydesigned for use in smoking tubes or pipes, and is in the nature of 11improvement upon the tobacco cartridge described and claimed in my priorPatent o. 1,144,824 dated June 29, 1915. 4

The cartridge of the present invention, in addition to having inherenttherein the various advantageous attributes incident to the cartridge ofmy earlier patent, also possesses certain manifest and well definedfeatures of novelty and utility which constitute, from a practical andcommercial standpoint, a distinct advance over all prior art tobaccocartridges, including that of my own earlier patent aforesaid.

In the cartridge of my earlier patent, the

filler was defined as being made up of to-- bacco leaves or portions ofleaves of substantial area superposed and compacted into a roll, thesaid filler being inclosed in a binder of smokable material. While thisprior cartridge in itself, in so far as its smoking qualities areconcerned, satisfactorily fulfils all the purposes for which it wasdesigned, the manufacture thereof in large quantities presented certaincomplex problems of a commercial nature involving among other factors,the maintenance of a minimum cost of production while attaining amaximum volume of output of the product. One of these problems residedin the difficulties encountered in providing reliable mechanical meansfor accurately handling and arranging the tobacco leaves or portions ofleaves of substantial area so as to produce a uniformly compacted andfree drawingroll in an expeditious, economical and practical way,especially when attempts were made to make the cartridges from acontinuous filler rod of tobacco.

After much laborious and very expensive experimentation conducted on thelines of practical commercial manufacture of the product, I finallysucceeded in accomplish-.

ing the solution of the difficult problems hereinbefore referred to, andam now able to produce in a thoroughly practical, expeditious andcomparatively inexpensive way, a tobacco cartridge for smoking purposesthat successfully fulfils the requirements of both the consumer and themanufacturer and wherein the tobacco filler is made up of tobaccoparticles or relatively small portions of tobacco, as distinguished fromleaves or portions of substantial area. The filler of the presentinvention is inclosed and compactly retained within an open-endedwrapper preferably composed of a material prepared to be sn 'oked orconsumed along with the filler, the; said tobacco particles beingindiscriminatly arranged and closely compacted into aZr-oll, but notdensely solidified, so that the sad particles will be interlocked, so tospeak, with the result that when the compacted filler is inclosed withinits wrapper the particles will not readily sift from the ends thereof,yet will permit of a free draft through the cartridge.

One of the prime objects of the present invention is, therefore, toprovide a smoking cartridge especially adapted for use in smoking tubesor ordinary pipes and wherein a sufficient quantity of relatively smallparticles of tobacco is compressed or compacted and inclosed andretained within a close-fitting open-ended wrapperso as to give to theconsumer a substantially long smoke in-a minimum length of cartridge,and wherein the tobacco particles will be so compacted within itswrapper that said particles will not readily sift out even should theparticles become more or less dry, and wherein, during the act ofsmoking, the cartridges will burn slowly and uniformly.

I am aware that it has been proposedin numerous prior art patents toprovide smoking cartridges wherein the tobacco filler is more or lessloosely inclosed within wrappers of various kinds from which wrappersthe tobacco is to be expelled into a pipe, a suitable tool, such as aplunger, being employed to force the tobacco from its wrapper into thepipe. It has also been proposed to densely compact or solidify tobaccoin the form of cartridges with draft openings molded therein. It hasalso been proposed to solidly compress blended grades of tobacco into astick or roll from which a section may be broken and then, after rollingin the hands to loosen up the tobacco particles of p the broken-offsection, the latter is packed into the pipe in the usual way. It hasalso wherein portions of tobacco are wrapped or inclosed in a. tobaccoleaf or other wrapper.

with the ends of the wrapper folded over or gathered about the oppositeends of the cartridge to prevent the tobacco from spilling out of theends of the wrapper. It has also been proposed to inclose a pipe chargeof tobacco within a wire cage, which wire cage with its tobacco chargeis adapted to be inserted bodily into the pipe; and other forms ofcartridges and tobacco sticks have been proposed, but I lay claim tonone of these, for, so'far as I am aware, such prior forms of cartridgeshave never gone into general use, and have never met with favor, chieflybecause they are either too costly to manufacture, too inconvenient for,the smoker or absolutely impractical "'fro both the standpoint of themanufacturer and the user.

My improved smoking carthidge is distinguished from all prior for ns ofwhich I am aware in that the tobacco filler is made up of relativelysmall particles of cut tobacco that are indiscriminately arranged andclosely compacted so as to cause the said particles to interlock andthus form a substantially stable, but not densely solidified pipe-chargehaving suflicient porosity to permit of a draft therethrough, the saidfiller being confined and retained in a closefitting open-ended wrapper.In its preferred form, the 'cartridge,-while it is initiallysufiiciently closely compacted to maintain its shape against moderate:pressure when standing alone, yet it may be slightly further compressedwhen forced into a pipe or smoking tube so as to form 'a snug fittherein and allow of a draft therethrough. The open-ended wrapper withinwhich the tobacco filler is inclosed and retained is so applied as tohave a suiiiciently snug fit whereby to prevent displacement on thecartridge when the covered cartridge is forced into a pipe or smokingtube.

I have illustrated a preferred embodiment of my invention in theaccompanying drawing, wherein,

Figure ,1, is a perspective view of a por- I tion of a continuousfiller-rod of tobacco inclosed within a'wrapper, the view showing one ofmy improved cartridges out therefrom. Fig. 2, is a perspective viewshowing the compacted filler charge standing alone the wrapper beingremoved. Fig. 3, is a perspective view of one of my improved cartridgescut or broken open to illustrate, in a way,'how the tobacco particlesare interlocked, theview being on a one manner of mit withdrawal of acartridge. Fig. 5, is a longitudinal sectional view showing one form ofsmoking tube or implement with one of my improved cartridges insertedtherein, one end of the cartridge being left slightly projected from,the mouth or bore of the pipe to illustrate in a Way, how that portionof the cartridge within the bore of the pipe has been furthercompressed.

In the accompanying drawing, wherein I have illustrated a preferredembodiment of the invention, t-he'reference numeral 10 designates afiller-rod of tobacco inclosed within a close-fitting wrapper 12 whichis pref: erably composed of a material prepared to be smoked along withthe filler, the cartridge being smokable as a whole.

}The reference numeral 13 designates generially one of my improvedtobacco cartridges which has been cut from the tobacco filler-rod bysevering the latter transversely of its length to provide, what I mayterm a pipe-charge section, the ends of which preferably present planesurfaces. The said filler-rod together with its Wrapper preferably hasa. cross-sectional shape and diameter substantially co-extensive withthe shape and diameter of the borel l of the pipe or tube 15 in whichthe cartridge is to be smoked, yet being slightly compressible so as tofit snugly into the said bore.

The tobacco constituting the filler-rod 10 is made up of relativelysmall particles or portions of cut tobacco of any desired blend that areindiscriminately arranged. The 100 said tobacco particles are, however,closely compacted, in a manner to cause the particles to interlock withone another, but are not densely solidified, the degree of compressionexerted upon the tobacco mass constituting the filler being such as tocause the particles to interlock and form a substantially stablecartridge that will maintain its shape against moderate pressure whenstanding alone. The compression, however, is not so great as to destroythe porosity of the cartridge, the compactness being just sufiicient tohold the tobacco particles together when in the cartridge form, yetpermitting of a draft therethrough.

I prefer to make the cartridge in the form of a relatively shortcylindrical roll, as shown in Fig. 1, having a diameter substantiallyco-extensive with the diameter of the bore of the pipe or tube in whichit is to be 129 smoked and preferably of such length that when thecartridge is'inserted in the pipe a space may be maintained between oneof the plane ends of the cartridge and the bottom of the pipe bowl, asmore clearly illustrated the filler. This wrapper ma consist of thinpaper, such as now emp oyed in the manufacture of cigarettes, or I mayemploy a composition wrapper made up of tobacco fibers in the form of asheet or sheets like or resembling paper, or I may employ a paperwrapper saturated W1th tobacco juices or tobaccoextract to simulate leaftobacco.

The tobaccolfiller 10 of my improved cartridge may be said to be readytamped in that it is inserted in the pipe in just the condition in whichit is given to the consumer, except that it may be slightly furthercompressed in the act of inserting it in the pipe, and one of thepeculiar characteristics of the cartridge is that when it is lighted andthe tobacco begins to burn,;th, e tobacco particles will not expandappreci ably or fluff out and sloughoif as is the case with tobacco asordinarily packed in a pipe by hand, and there is not present,therefore, in my improved cartridge, that objectionable featureuniversally experienced by pipe smokers generally of having the burningtobacco expand and crawl or slough out over the edge of the pipe andonto the clothes of the smoker, with the resultant annoyances anddangers.

A further characteristic of my improved compacted filler charge, whichseems to be due to the manner in which the tobacco particles arecompacted and interlocked, is, that the ash of the burning fillermaintains its cartridge form during the smoking process and this ashmore or less tenaciously clings to the burning charge until thecartridge is substantially consumed; and a still further characteristicis that' the burning charge oes' not need to be tamped from time totime, during the smoking process, as is the usual custom in the case ofpipes filled by hand with loose tobacco, since the tobacco particleswhen originally compacted, according to my invention, seem to becomeinterlocked or interconnected in such a way that the cartridge maintainsits original form until it is entirely consumed. Furthermore, thecartridge wrapper which is consumed along with the filler and which isinterposed between the filler and the wall of the pipebore seems toprevent the usual accumulation of a charred incrustation within the bowlof the pipe, an objection so common in cases where tobacco is packedinto the pipe in the ordinary way, so that with my improved cartridgethe bore of the pipe does not materially decrease in diameter, throughprolonged smoking thereof, hence the cartridges, which are ofsubstantially uniform diameter. may be readily inserted within the pipeat all times, even after such prolonged smoking thereof.

Inasmuch as each individual pipe-charge section or cartridge contains asubstantial quantity of tobacco, due to the fact that the tobaccoparticles are closely compacted, the said cartridges not only burnuniformly and slowly, but each cartridge will give the consumer arelatively long and cool smoke notwithstanding the fact that they arecomparatively short, and, since the tobacco filler does not sift out ofits wrapper when inserted in the pipe the usual objectionable soggyheel, so common in' pipe smoking, when the pipe is filled in theordinary way, is entirely avoided.

In marketing the cartridges I may of course pack them in any suitableform' of container, but I prefer to arrange a plurality of thecartridges end to end and inclose them "in a wrapper or envelop 16, suchas set forth in my hereinbefore mentioned prior patent, whereby toprovide a handy pocket-package, which wrapper may be torn away somewhatas shown in Fig. 4, to permit withdrawal of the cartridges one at a timeas desired.

What I claim is:

1. As a new article of manufacture, a tobacco cartridge of substantiallycylindrical form to fit within a pipe bowl and a wrapper therefor ofsmokable material having both ends open, said cartridge being composedof tobacco particles compacted to interlock whereby the particles aremaintained from sifting out and yet permitting of a draft therethrough,the ends of said cartridge forming a plane surface so that when forcedinto a ,pipe bowl a space may be maintained between one end of thecartridge and the bottom of the bowl.

2. As a new article of manufacture, a tobacco cartridge adapted to besmoked in a pipe or smoking tube, comprising a pipecharge section of atobacco filler-rod composed of relatively small indiscriminatelyarranged tobacco particles, closely compacted so asto cause the saidparticles to interlock and form a substantially stable, but not denselysolidified charge having sufiicient porosity to permit of a drafttherethrough, the said charge-section being confined and retained in aclose-fitting open-ended wraper. p 3. As a new article of manufacture, atobacco cartridge adapted to be smoked in a pipe or smoking tube,comprising a pipecharge section of a tobacco filler-rod composed ofrelatively small indiscriminately arranged tobacco particles, closelycompacted so as to cause the said particles to interlock and form asubstantially stable, but not densely solidified roll'having sufficientporosity to permit of a draft therethrough, the

said roll being confined and retained in a close-fitting open-endedwrapper composed of a material prepared to be consumed in the pipe alongwith the filler.

4. As a new article of manufacture, a tobacco cartridge adapted to besmoked in a pipe or smokmg tube, comprising a pipe-' charge section ofa. substantially cylindrical tobacco filler rod composed of-relativelysmall indiscriminately arranged tobacco particles, closely compacted soas to cause the said articles to interlock and form'a su'bstantlallystable, but not densely solidified roll, having sufiicient porosity topermit of a draft therethrough, the said rollbeing confined and retainedin a close-fitting openended Wrapper composed of a material preared tobeconsumed along with the tobacco E1161, thesaid cartridge having across-sectional shape anddiamete'r substantially coextensive with theshape and diameter of the bore of the pipe or tube in whichit isto besmoked and being slightly compressible .so as tofit snugly into the saidbore.

5. A tobacco cartridge composed of tobaccov articles indiscriminatelyarranged and su clently closely compacted to maintain its shape againstmoderate pressure Witnesses:
